EXTRACTOR FOR BREAKDOWN GUNS.

Specification of Letters Patent.

Application filed August 16, 1919. Serial No. 318,009.

To all whom it may concern.

Be itknown that I, FRANK F. BURTON, a citizen of the United States,residing at Mount Carmel, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in Extractorsfor Breakdown Guns; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this application,and represent, m-

My invention relates to an improved extractor for breakdown guns, theobject being to provide simple and reliable means for positivelyoperating the extractor in case the cartridge sticks beyond the capacityof the extractor-spring to extract it from the chamber of thegun-barrel.

With these ends in view, my invention consists in certain details ofconstruction as will be hereinafter described and pointed out in theclaims.

In carrying out my invention, as herein shown, I employ what I shall,for want of a more convenient term, call a rocking extractor-actuatorwhich consists of a crescentshaped plate 1 having its inner face formedwith a retaining-notch 5 receiving the reach of a staple 6 by which thepart is loosely held in lace in a shallow vertical segmental slot 7ormed in the center of the shoe 8 mounted upon the rear end of theforearm 9 of the gun. As thus mounted the extractor-actuator hassliding, rocking movement in the staple 6, within the limits imposed bythe length of its notch 5.

My improved extractor-actuator is positioned to engage at its upper endwith the forward end of an extractor-plunger 10 projecting through theforward end of a long, axial bearing-hole 11 formed in a lug 12depending from the breech end of the gunbarrel 13. The rear portion ofthe said plunger is encircled by a helical extractorspring 14: theforward coil of which impinges upon a shoulder 15 formed by reducing thesize of the hole 11 to the diameter of the plunger, while the rear coilof the said spring impinges upon the forward face of the plunger-head16'the rear face of which engages with the forward end of the stem 17 ofan upstanding extractor-head 18 which normally fits into a slot 19 inthe rear end of the gunebarrel. The said plunger head 16 and stem 17have a sliding fit in the hole aforesaid. The upper edge of theextractorhead' 18 is shaped to engage with the rim 20 of a cartridge 21when the same is fully inserted into the chamber of the gunbarrel 13 asshown in Fig. 2. I

The extractor-stem 17 has its lower face cut away to produce acatch-shoulder 22 and a stop-shoulder 23 located toward its forward endand co-acting in sequence with the nose 24. of a pivotal extractor-catch25 located within a vertical slot 26 in the lug 12 and hung upon apivot-pin 27 passing through the same. is formed with an upstanding lug28 entering a cut 29 in the lower face of the extractor-stem 17 andpreventing the same At its rear end the catch from rotating. Atitsforward end the catch 25 1s formed with a round transverse hole 30'receiving an operating-pin 31 which moves up and down 1n a slightlycircular path as the catch swings upon its pin 27, clearance beingprovided for this movement by holes 32 (Figs. 2, 3 and 4) in the sidewalls of the slot 26 in the lug 12 depending from the barrel 13. Theprojecting ends of the pin 31 enter clearance-recesses 33 formed inthe inner faces of the side walls of the receiver 3a as best shown inFig. 3. When the gun is broken down, as shown in Fig. at, the upperfaces of the projecting ends of the pin 31 engage with the upper walls35 of the said recesses 33 with the effect of positively rocking thecatch 25 upon its pivot-pin 27 against the tension of a helicalcatch-spring 36 located in a circular hole 37 formed to receive it inthe lug l2 and leading out of the rear wall of the slot 26 formedtherein for the reception of the catch 25. A heavy pin 38 mounted in thereceiver and having its upper face cut away as at 39 to clear theplunger 10, fits into a semi-circular groove &0 in the front end of thelug 12 and provides a fulcrum upon which the barrel turns in breakingdown the gun. To return now to the crescentshaped extractoractuator a,its lower edge is engaged by the forward edge ll 0f the floor 42 of thereceiver 34L.

As thus constructed and arranged, the rocking extractor-actuator t isinterposed between the forward end of the receiver and the forward endof the extractor-plunger at a point in front of the fulcrum on which thebarrel and the receiver turn, so that when the gun is broken down, thereceiver positively rocks the actuator which slides in a circular pathin the staple 6, so as to engage its upper end with the forward end ofthe plunger 10 and positively force the same from front to rear providedthat the extractor-spring 1.4: did not move the plunger 10, and hencethe extractor, rearward as soon, in the opening of the gun, as the engagement of the projecting ends of the pin 31 with the upper walls 35 ofthe recesses 33 operated the catch 25 to retract the nose 24 thereoffrom the catch-shoulder 22 of the extractor. When the gun is closed, theface 13 of the receiver at will engage with the curved lower corner ofthe rear face of the extractor-head 18 and force the same forwardagainst the tension of the spring 1a which is in this manner placedunder the compression required for the normal extraction and ejectionofthe spent cartridges. Just as the extractor nears the limit of itsforward 'movement, its catch-shoulder 22 is engaged by the nose 2 1 ofthe catch 25 acting under the influence of its spring 36. During thisclosing movement of the barrel and the forward movement of theextractor, the forward end of the plunger 10 engages with the upper endof the actuator 4t and rocks and slides the same back into its normalposition in which it is shown in Fig. 2. It will. thus be seen that whenthe gun is broken down, the actuator acts to positively operate theextractor in case the spring fails to operate the same automatically. Itis expected, however, that in the ordinary operation of the gun, thespring will operatethe extractor to extract the cartridge from thechamber, the actuator being provided only to insure the starting of thecartridges in case they stick. Normally the actuator operates, butoperates idly.

I claim 1. A break-down gun having a receiver, a forearm, a shoe mountedthereupon and formed with a vertical segmental slot, a barrel fulcrumedin the receiver, a cartridge-extractor, a crescent-shaped, rockingextractor-actuator located in the said segmental slot in position to beoperated by the said receiver for positively pushing the said extractorrearward when the gun is broken down and formed upon its concaved innerface with a notch by means of which its sliding rocking movement islimited, and a staple mounted in the said shoe and embracing the saidextractor-actuator for holding the same in the said slot and limitingits rocking movement.

2. A break-clown gun having a receiver, a forearm, a shoe mountedthereupon and formed with a vertical segmental slot, a barrel fulcrumedin the receiver, a cartridge-extractor, a spring therefor, anextractor-plunger, an extractor-catch, a crescent-shaped, rockingextractonactuator loeated in the said segmental slot in position to beoperated by the said receiver fOr positively pushing the said plungerrearward when the gun is broken down and formed upon its concaved innerface with a notch by means of which its sliding rocking movement islimited, and a staple mounted in the said shoe and embracing the saidextractoractuator for holding the same in the said slot and limiting itsrocking movement.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses. I
